Abstract
<jats:p>The article presents the results of a floristic study of technogenically disturbed territories associated with industrial enterprises in the East Kazakhstan Region (EKR) and assesses the current ecological state of vegetation in these areas. The aim of the study was to evaluate the ecological features and current condition of flora in disturbed industrial territories based on an analysis of species composition and the ecological structure of plant communities at seven major non-ferrous metallurgy enterprises in the East Kazakhstan Region. The object of the study was the flora of technogenically disturbed industrial sites. The research was based on field botanical surveys using floristic and ecological–cenotic analysis methods. The disturbed flora was found to comprise 253 species of woody and herbaceous plants belonging to 171 genera and 53 families. Three leading families were identified: Asteraceae Bercht. & J.Presl — 41 species (16.1%), Poaceae Barnhart — 24 species (9.4%), and Rosaceae Juss. — 23 species (9.0%), which are characteristic of the boreal–temperate flora of the Holarctic region. The study includes an ecological and morphological assessment of plant adaptation to environmental conditions and analyzes patterns of vegetation recovery in disturbed habitats. Ecological characteristics of the phytocenoses are presented, the distribution of species among ecological–cenotic groups is examined, and a botanical–geographical analysis of the flora of technogenically disturbed territories is conducted. The obtained results expand current understanding of vegetation formation under technogenic impact and provide insight into the present state and ecological organization of technogenic flora.</jats:p>
